Iron Pump utilizes "Super Nitric Oxide" ION-3 Nitrate Technology to open up blood pathways into the muscles, improving the effectiveness of the ordinary molecule. As the world's first molecularly-modified arginine, L-Arginine Nitrate is a fusion of l-arginine and nitric acid that increases blood flow to enhance distribution of nutrients. (In general, nitrates open up blood vessels to help promote nutrient delivery and amplify athletic performance, leading to improved strength, recovery and muscle mass.) Arginine creates nitric oxide to support vascularity and strength while supporting healthy growth hormone levels.
